Primary sarcomas of the liver are unusual neoplasms developing in adults. They constitute a heterogeneous group of neoplasms including undifferentiated embryonal sarcoma. Patients usually present with an abdominal mass and abdominal pain. Case 1: A 53-year-old woman presented with abdominal pain. Computed tomography showed an occupying mass in the right lobule and an intra-auricular multi-lobulated mass suggestive of a secondary deposit. Biopsy of the hepatic lesion revealed undifferentiated embryonal sarcoma. Despite radiotherapy and supportive measures, her overall status progressively worsened until cardiac arrest. Case 2: A 41-year-old woman presented with hepatomegaly. Abdominal imaging showed cystic lesions in the right hepatic lobule with multiple septae. The patient underwent extended right hepatectomy and a histopathological study reported high-grade undifferentiated embryonal sarcoma. Two years after surgery, a new cystic lesion in the surgical site was recorded and chemotherapy was scheduled. The lesion remained stable for three years when disease progression was observed and second-line chemotherapy was initiated. Although undifferentiated embryonal sarcoma of the liver has poor prognosis, early diagnosis is essential to increase the chances of survival. Currently, surgical resection and chemotherapy are the primary treatment modalities.
